Hi Krystal,
Don't be discouraged. As a lot of people above have said, smaller populations sometimes take a little longer. I'm talking to you with my investor hat, and my broker hat on here...(I'm both!)
Consider freshening your pictures, they most certainly are not bad, but once the snow is gone, and the sun is out the place will look way more inviting. The rooms look really big, maybe even consider doing some digital staging? There are some incredible options that look really good (I use them sometimes in Million dollar homes for sale, especially on roof top decks in the winter....) and will help you sell the size of the place.
I agree with making sure folks know the pet deposit is refundable, and I also support you removing the pet rent. My guess, looking at the community, is that many people have pets. Keep the audience as wide as possible.
Can you stretch the coverage? Who is your market? Can you directly market to employers in the area, or even to companies in neighboring areas? Approach local schools and hospitals, and ask if you can post in staff rooms or common areas.
The most important comment I have, is be careful about the tenant you finally choose. Sometimes, when it takes a little longer to find a tenant, it can be tempting to take the first one that comes along.... do your due diligence, and don't be afraid to say no. A bad tenant can cost you more than vacancy..
Get creative with your advertising, don't rely just on the internet, freshen the presentation, and make a smart choice about the tenant when they come along. Stay the course, and you'll be just fine. Best of luck!!
